OPEN GAS-BURNER.

SPECIFICATIQN forming part of Letters Patent No. 417,765, dated December 24,-1889a Application tiled July 16, 1889. Serial No. 317,744. (No model.) Patented in England September 29, 188'?, No. 13,222.

To @ZZ whom t may concern.-

Be it known that I, GEORGE EENEsT WIRIGHT, a subject of IIer Majesty the Queen of Great Britain, residing at Birmingham, in the county of \Varwick, England, have invented certain new and useful Improvements 1n Open Gas-Fires, (for which I and my brother, John Frederic IVright, have obtained a patent in Great Britain, No. 13,222, bearing date `September 29, V1887,) of which the following 1s a speciiication.

rThis invention of improvements in open gas-:fires has reference to improved means for collecting and radiating the heat from the nre, and my said invention is illustrated by the accompanying drawings, of which-' Figure l represents in front elevation partly 1n section, Fig, 2 in sectional side elevation, and Fig. 3 in sectional plan, an open gas fire o r stove constructed according to this invention. Fig. 4t shows in front and side elevatlon one of the special gratings or iiues of the said gas-iire separately, and Fig. 5 is a perspective view of the brick or other back of the same separately.

The same letters of reference indicate corresponding parts in all the gures.

a is the outside metal casing of the gas iir'e or stove, which may be of any suitable shape or design, and in the one shown there is nothing new, as my invention does not consist in this portion.

Z is the atmospheric gasburner, the name from which issues at the nozzles c at the upper side thereof and heats the perforated vertical iues or gratings D and the brick or other back E of the stove, and then passes up through the holes f and passage g and out through the usual outlet h. These iiues or gratings D form an important part of this invention. They are by preference made of cast-iron; but they may be made of plu mbago or other suitable substance. I prefer to make them of or about the form illustrated on the drawings, which is roughly a trough shape in cross-section, and it is important that the corrugated portions or hollow swells d d2 cl3 should be present; but the exact outline or number of corrugations may be varied, as may also the amount of curve in cross-section, as seen in Fig. 3, even so far as to a straight plate in horizontal section with in all cases the perforated corrugations or swells, of which there may be any convenient number. I use one or more gratings D,according to the width of iire required.

The gratings D may be placed in position and there secured by means of two pins d4, cast or formed in one piece with the parts D. The pins d4 enter the holes f in the brick or other back E, and are sufciedtly long to allow of the grating being lifted up when the lower end (Z5 is dropped behind the front a of the frame a; but l do not confine myself to the use of these pins, as other means of fastening the gratings D are available. I have found the parts D to give thebest effect when made slightly smaller at the top than at the bottom, and I prefer the variegated surface both in regard to configuration, general outline, and perforations. The effect of the llame as it passes upwardly is to make the grating D red-hot. The several sections D may, if preferred, be combined into a less number of parts than shown, or even into one piece or casting. The brick or other back E is made to agree in width with the required number of gratings D, and I form upon the top of this brick a flange or top e', which has perforations f, in which the upper ends of the gratings D engage. The object of this Iiange or top e is to arrest the heated gases as they pass from the perforated parts D to the outlet-pipe 7L, and to deect the heat downwardly onto the gratings D, and thus increase the efficiency of the fire. The heating-surface of the brick or other back E is increased by the corrugated ribs c2, formed in the front thereof, and which are covered by the gratings D.

Vhat I claim as my invention, and desire to secure by Let-ters Patent, is-

l. In an open gas-stove, the combination of the burner, the vertical trough-like lines D above the same, the-iire-brick E,constituting the rear wall of each of the nues, said brick having a flange e at its upper end, the said In testimony whereof I have signed in the fines engaging said ange, substantially as presence of two subscribing witnesses. described.

2. In combination, the burner, the vertical iues D, and the fire-brick formed with the lip e and the ribs e2, the said lues fitting over said ribs and engaging the lip e at their upper ends, substantially as described.
